Question

A 10kg box full of 1943 original Turtle Man comics falls from loading platform to a spring loaded platform 3 m below. Assume that there is no friction and that the spring can be modeled using Hooke's Law determine the speed of the block just before it hits the spring. Determine the spring constant if the mass compressed the spring 0.5 meters before coming to rest.

Answer 1

Answer

In equilibrium

mg =kx

Spring constant

$K=\frac{mg}{x}\\=\frac{10\times9.8}{0.5}\\=196N/m$
